HEVC video decoding broken with B-frames
When Edge Chromium playing HEVC video, sometimes video will be similar to stuttering but audio is normal. To find out the cause of the problem, I test to playback many HEVC video, include videos ...
I have the same issue om my machine. Even when using the Edge Chromium Dev build Version 89.0.767.0 (Official build) dev (64-bit).
does you have the link of a video who do that (for reproducing purpose, if you report it by the browser don't forget this)
- There are example videos online, a quick web search would reveal them
I encoded a video in the HEVC codec. I added the file to this message.
To test this, you can make a simple HTML file that plays this video in the Edge browser.
<body> <video src="PathToVideo\BigBuckBunny.mp4" type="video/mp4" controls></video> </body>- I just drag and dropped this onto an Edge tab and i get extremely laggy playback

700KB H.265 clip with HEVC extension installed on Windows (.MP4)I can also reproduce it with your sample.
I can also confirm with certainty on my end that it has to do with the HEVC b-frames because when I encode a video with "b-frames=0" it plays fine without any stutter.
